3-Mar-2016 Pushing boundaries
Solid-liquid interface studies have a long history at EMSL. The insights gained from this research spans areas including terrestrial ecosystems, energy materials, aerosols and biological systems. With improved understanding of interfacial events, scientists working at EMSL have developed more predictive models and made significant advances in addressing real-world challenges. EMSL's focus on solid-liquid interface research has pushed the development of new instruments and techniques to better study these complex surfaces for even greater scientific results.
25-Feb-2016 Fermilab scientists discover new 4-flavor particle
Scientists on the DZero collaboration at the US Department of Energy's Fermilab have discovered a new particle -- the latest member to be added to the exotic species of particle known as tetraquarks.
22-Feb-2016 Updated workflows for new LHC era
After a massive upgrade, the Large Hadron Collider (LHC) is smashing particles at an unprecedented 13 teraelectronvolts (TeV) -- nearly double the energy of its previous run. In just one second, the LHC can now produce up to 1 billion collisions and generate up to 10 gigabytes of data.
To deal with the new data deluge, researchers working on the LHC's ATLAS experiment are relying on updated workflow management tools developed primarily by Berkeley Lab researchers.
19-Feb-2016 Physicists zoom in on gluons' contribution to proton spin
By analyzing the highest-energy proton collisions at the Relativistic Heavy Ion Collider (RHIC), a particle collider at the US Department of Energy's (DOE) Brookhaven National Laboratory, nuclear physicists have gotten a glimpse of how a multitude of gluons that individually carry very little of the protons' overall momentum contribute to the protons' spin.
19-Feb-2016 New satellite with superior X-ray vision launched
Although the star-covered night sky is regarded by many as a synonym of serenity, the cosmos is in fact a rather hostile place. It hosts many extreme environments that would instantaneously eradicate any life nearby. A new space mission is about to reveal this violent nature in greater detail than ever before: on Feb. 17, the Japan Aerospace Exploration Agency launched its ASTRO-H satellite -- a very precise and sensitive eye for X-rays emerging from hot and energetic processes in space.
17-Feb-2016 Scientists start small on the road to building gigantic DUNE neutrino detector
The planned Deep Underground Neutrino Experiment will require 70,000 tons of liquid argon, making it the largest experiment of its kind -- 100 times larger than the liquid-argon particle detectors that came before it. Before building this unprecedented machine, scientists understandably want to make sure it's going to work. That's why members of the international DUNE collaboration recently began taking data using a test version of their detector.
8-Feb-2016 Three ways to bust ghostly dark matter
Dark matter hunters around the world pursue three approaches to look for fingerprints of ghostly WIMPs: on the Earth's surface, underground and in space. Researchers from the Department of Energy's SLAC National Accelerator Laboratory will take part in a discussion of the global search for dark matter particles at this year's AAAS Annual Meeting, to be held Feb. 11-15 in Washington, D.C.
4-Feb-2016 Canfield to head APS Condensed Matter Division
Ames Laboratory physicist Paul Canfield has always been a vocal proponent of his field, condensed matter physics, but he's about to take it up a notch. In March, Canfield will begin a four-year leadership stint heading up the Condensed Matter Physics Division of the American Physical Society. APS recently announced that Canfield had been elected vice-chair of the CMP division.
3-Feb-2016 A mile-deep campus
Students at South Dakota universities can study physics at Sanford Underground Research Facility, which doubles as essentially the first college campus located a mile underground.
28-Jan-2016 Is the neutrino its own antiparticle?
Almost every particle has an antimatter counterpart: a particle with the same mass but opposite charge, among other qualities. But certain characteristics of neutrinos and antineutrinos make scientists wonder: Are they one and the same? Are neutrinos their own antiparticles?
25-Jan-2016 Cracking cases
A group of nuclear detectives at the Department of Energy's Oak Ridge National Laboratory takes on tough challenges, from detecting illicit uranium using isotopic 'fingerprints' to investigating Presidential assassination conspiracies. 'A very big capability at Oak Ridge exists for nuclear analytics, all the way from helping commercial production of nuclear power to making sure the world's nuclear materials are properly accounted for,' said ORNL's Joseph Giaquinto, leader of the Nuclear Analytical Chemistry and Isotopics Laboratories.
25-Jan-2016 How to find and study black holes
Black holes sound too strange to be real. But they are actually pretty common in space. There are dozens known and probably millions more in the Milky Way and a billion times that lurking outside. The makings and dynamics of these monstrous warpings of spacetime have been confounding scientists for centuries.
21-Jan-2016 Higher speed, more precision
In just a little over a year of operation, the US Department of Energy Ames Laboratory's dynamic nuclear polarization (DNP) solid-state nuclear magnetic resonance (NMR) spectrometer has successfully characterized materials at the atomic scale level with more speed and precision than ever possible before.
21-Jan-2016 Explore galaxies far, far away at internet speeds
Scientists have released an 'expansion pack' for a virtual tour of the universe that you can enjoy from the comfort of your own computer. The latest version of the publicly accessible images of the sky, which can be viewed using an interactive Sky Viewer tool, roughly doubles the size of the searchable universe from the project's original release in May.
19-Jan-2016 ORNL researchers use neutrons to gain insight into battery inefficiency
Scientists at Oak Ridge National Laboratory are improving the lifetimes of rechargeable batteries that run on lithium, a small atom that can pack tightly into graphite anode materials. The valuable ions are depleted as a battery charges, and they are also lost to the formation of a thin coating on a battery's anode during initial charging. ORNL researchers used two powerful neutron science facilities to try to understand the dynamics behind this phenomenon.
15-Jan-2016 ORNL's thermal cameras snoop beneath surfaces to reveal materials' secrets
In 1995, the Department of Energy's Continuous Fiber Ceramic Composite program, led by Oak Ridge National Laboratory, bought a high-speed infrared camera -- one of the first available for purchase outside the military. Since then, ORNL has acquired at least 10 additional IR cameras for use in a spectrum of projects. The cameras have mapped changing temperatures as heat flows through objects from gears to artwork.
8-Jan-2016 SLAC's Stanley Brodsky shares Pomeranchuk Prize for theoretical physics
Stan Brodsky, a professor of particle physics and astrophysics at Stanford University and the Department of Energy's SLAC National Accelerator Laboratory, has received the 2015 Pomeranchuk Prize from the Institute for Theoretical and Experimental Physics (ITEP) in Moscow, Russia. He shares the award with Russian physicist Victor Fadin.

16-Dec-2015 A collaboration bears fruit as W7-X celebrates first research plasma
Scientists from the US Department of Energy's Princeton Plasma Physics Laboratory (PPPL) and other national laboratories joined colleagues from around the world at the celebration for the first plasma of the Wendelstein 7-X (W7-X) stellarator at the Max Planck Institute in Greifswald, Germany.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
